Planning and Design Inc. engineers for both commercial and residential Photovoltaic
(PV) system. This enables owners to generate
some or all of their daily electrical energy demand on their own site,exchanging daytime excess power for future energy needs (i.e. nighttime usage). The stucture remains connected to the electric utility at all times, so any power needed above what the solar system can produce is simply drawn from the utility. PV systems can also include battery backup or uninterruptible power supply (UPS)
capability to operate selected circuits for hours or days during a utility outage.
